TO ALL WHOM IT MAY CONCERN:

Be it known that I, JEHU F. WOTRING, of Willey, in the county ofPreston, and State of West Virginia, have invented an improvedCar-Coupling; and I do hereby declare the following to be a full, clear,and exact description thereof, reference .being bad to the accompanyingdrawings, making part of this specification, in 'which- D Figure 1 is avertical section, taken longitudinally through the centre of theimproved coupling.

1 Figure 2' is a similar section of the same parts, showing the link inthe act of coupling with the pin.

Figure 3 is asection taken in the horizontal plane indicated by redlines a: rt in fig. 1, showing the link bearing against its abutment.

Figure 4 is abottom view of the pivoted guide-box and link abutment.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates ,to certain novel improvements in theconstruction of that class of railroad carcouplings which are adaptedfor self-couplingavhen cars are brought together.'

The nature of my inventionfconsists in pivoting the coupling-pin to avertically vibrating bar, which is .appliedon the top of thecoupling-box in such manner that said pin shall hang freely, and alwaysmaintain a vertical position, except when pressed ,back by theintroduction of the link, and in the employment, in conjunctiontherewith, of a contrivance which will receive the end of thecoupling-link when cars'are broughttogether, and guide this link in aposition for receiving the coupling-pin, and allowing "this pin to dropin its place, as will be hereinafter described. It also consists in acoupling-pin which is pivoted to its couplingbox in such manner that itwill hang free in a vertical position, and also beallo wed to rise andfall bodily, andin the employment in conjunction with such pin of adevice which shall serve the double purpose ofa guide for thecoupling-link, and also of an abutment ifor resisting the backwardthrust of this link in the act of coupling two cars together, as will behereinafter described. It also consists in so constructing the linkguide and abutment that it shallalso serve as a means for properlyguiding the lower end of the pivoted coupling-pin into thecoupling-link, .as will be hereinafter described. v

To enable others skilled in the art to understand my invention, I willdescribe its construction and operation. i

In the accompanying drawings, A represents a coupling-box or draw-head,which is constructed with a flaring 'mouth, A, witha straight,rectangular :throat or passage, it, through it for receiving and guidingthe coupling-link G into the box to receive through it the coupling-pin.This box or head'A has also an oblong slot, a, made vertically andcentrally through it, of suflicient width to allow the coupling-pin O tovibrate freely in it, and to maintain a vertical position, as shown infig. 1. This slot (1 is made through the couplingborA, so as to have itsfront end terminate in the solid head A, and thereby form a strongabutment for, the coupling-pin above and below the throat h when thispin stands in a verticalposition. Said slot should be made of suflicientlength to allow the lower end of the pin 0 to be moved back to theposition shown in fig.

2 by the end of th e link in the. act of coupling cars together. Inevery other respect the coupling-box or drawhead may be constructed andconnected to the cars in the I usual well-known manner. The coupling-pinG is a round bar of irdi'a, having perforated headptc which a chain maybe connected for conveniently lifting the pin from the platform of a carwhenit is desired to unconple. This pin 0 is connected by a pivot, 0,near its upper end or head, to a vertically vibrating bar, 13, which isarranged on top of the coupling-box A, attached at its rear end to thisbox by a-lug, a, and transverse pivot cl, as shown in figs. 1 and 2.This bar B is a plane passing vertically and longitudinally through thecentre of the coupling-box, and its front end'is forked to receive andproperly hold the pin C, and to allow this pin to vibrate freely andassume a vertical position when unrestrained. Whenone end of thecoupling-link G is thrust through the throat of the box A it will strikethe pin (Land nlove thclowcr end of this pin backward until it dropsthrough the link,.and assumes the position shown in fig. 1. Ifcircumstances'i'ould always allow thelink to be introduced in a straightline intoits box A, the coupling-pin, as above described, would alwaysdrop through the link and effect a coupling;

'but under some circumstances the link will enter its box iii an obliqueline to the longitudinal central plane thereof, and thus more on oneside or the 'otherof-the end of its pin, V To remedy this I employ aguide block, Q whieh is arranged at a proper point, in line with thethroat k and in rear of the pin 0, and which is pivoted to the bar E bya transverse pin, f, so that its'front end can rise and fell freely. Thebottom of this block is recessed so as to form two flaring side-jaws, gg, and a groove, 9', as shown in the bottom view, fig. 4. The jaws g aredesigned for receiving between them and guiding the end of the link G asthis link is moved back I far enough to allow pin 0 to drop into it,shown in fig. 2. The groove g is designed for receiving and guiding thelower end of pin 0 during the not of-moving the link back to apositionfor receiving this pin. The block Dserves as a means for centring thelink, and also the lower end of the coupling-pin, so that the latterwill be brought directly over the space through the link, and caused todrop therein without fail. When the link is forced hack into thecoupling-box it will press the lower end of the pin C against thepivoted block D, so as to raise this block and allow the end ofthe linkto enter it, as shown'in fig. 2. When the pin 0 drops into the link, andthe latter is drnwnoutwnrd, the block D will drop and serve as anabutment for the link for holding it out in place during the act ofcoupling two cars together.

Having described my invention, what I claim as new, and desire to securebyLetters Patent, is-- 1. The combination of the hinged bar B, hingedpin C, hinged guide D, substantially as and for the pur pose described.I v

2. In combination with the pivoted pin (1, which is allowed to swingfreely about a pivot, c, I claim the recessed guide-block D, for guidingthe pin 0 and link G, substantially us described.

3. The construction of the block D, withside-jaws g g, and a groove, g,substnntitilly as and for the purpose described.

4. The manner, substantially as herein described, of insuring the properreln'tion of the link to the pin, and of coupling two cars together whensuch cars are moved towards each other, as set forth.
